So far, I have primarily discussed the format of books in terms of size, shape, ratio
of illustrations to text, and difficulty of text. Format also refers to aspects of the
physical makeup of a book such as the quality of binding and paper. The publishers’
hardcover editions are the highest-quality books. Covers are usually constructed of
heavy-duty cardboard covered with quality glossy paper. The pages of the book are
sewn together, and they are held inside the cover by sturdy endpapers that are glued
to the inside of the front and back covers. Designs that pertain to the book’s subject
or theme colorfully decorate the endpapers of many hardcover picture books.
Hardcover books are durable, and the high-quality paper ensures the best color
reproduction of illustrations. This is the best format for books that are going to be read repeatedly, such as picture books. However, hardcover books are expensive,
and a major loss occurs if classroom copies become misplaced or “permanently borrowed.”
Also, from a teacher’s practical point of view, they are heavy to carry and
take up a lot of shelf space.
